I took lots of pictures while volunteering in Greece. From Athens to the islands, shots of everything. I mixed up the pictures and handed about 30 to each small group of students. There were shots of people and places and activities. The students were to make up stories putting the pictures in order to create a work of fiction with the photos. I told them nothing about the pictures so they had to guess and then make-up the entire thing then present the story to the class. It worked and it gave them time to think on their own.
